Clean air is everyone's business. Beginning in 2010 federal regulation required on-road vehicles with diesel engines to meet stringent emission requirements, designed to improve air quality. Most diesel engine manufacturers moved forward with a technology called Selective Catalytic Reduction (SCR) to meet these requirements. Diesel Exhaust Fluid (DEF) is a key additive that the SCR system to work. If you purchase a car, truck, tractor or any diesel powered product with SCR technology, you need DEF.

Starting in 2010 diesel engines have to meet stringent emission requirements. Most diesel engine manufacturers have chosen a technology called Selective Catalytic Reduction (SCR) to meet these requirements. If you operate a vehicle or equipment that utilizes SCR technology, you need DEF.

Diesel Exhaust Fluid (DEF) is a very pure solution of urea which meets the automotive industry specification defined by ISO 22241. It is a clear liquid similar in appearance to water. DEF is safe to handle and use. Tt is not explosive, flammable, toxic or subject to any hazardous product regulations. When properly stored it a shelf life of 18 months.

Since you will use less DEF than diesel, the DEF tank will be smaller than the diesel tank. It will be clearly marked as DEF and is likely to be mounted next to or near your vehicle diesel tank. It is important that you do not put diesel in the DEF tank or DEF in your diesel tank. Some vehicles will have safeguards to ensure this doesn't happen but this might not be the case on all vehicles - so make sure to check!

Your vehicle will also be fitted with a DEF gauge near your fuel gauge so you will know when you need to fill up with the fluid. If you run out of DEF, your catalytic converter could be damaged which may void your vehicle's engine warranty.

Only fill DEF into the tank. Both nozzle and outlet are clearly marked.

Keep your DEF equipment clean and free from dust or dirt.

You do not need to wear protective clothing while filling DEF.

If overheated, DEF containers can be chilled by standing in water.

DEF freezes at 12 F

Only use DEF that has been delivered in dedicated, sealed DEF packages.
